To see people compare vehicle brands due to instrument panel similarities is mind boggling to me, not to mention timelines, and who did it first...
Reason why you're seeing companies going over to digital
(not a technical term for this subject because it's not about what its made of, but rather its purpose, which is to be MORE interactive) is to support new evolving tech (Level 4+ Autonomy). So just because BMW used some old technology to introduce new tech (6WB) doesn't mean anything except for the fact that no one knows why except for BMW themselves and their reason for it. Each company has its business strategy and they're planned for years ahead, so just because one brand stuck an obnoxious object in their car in 2012, won't make anyone e-brake their operation and change the game plan. Tesla did that shit because that was one of the only ways they'd get the publics (additional) attention.
Don't forget that these mega corporations have access to tech that we won't see for at least a decade, and the new tech that we're seeing is in fact old shit that's just due for release because the cow's are sucked dry, and aren't moooooin' shit.
/My opinion on comparing the use of tech in vehicles features and applications is dumb AF, especially when they have nothing to do with the actual driving dynamics.
